Marc Laroche stopped by to talk about the use of 3D in one of Xceed's new controls 3D Views for WPF. Watching Marc move the camera to adjust the display of the data (around 5:25) can give you an idea of where 3D can really be useful. Simply adjusting the position of the camera offers a new perspective rendered dynamically. There is no need to pre-render all of the desired views.
